music room design questions dimensions/flooring


I guess much has been written previously, yet I still seek answers to the following:

* for a room with dimensions of 13'1"(4.00m) width x8'8"(2.65m) height, what would the "best" length be? Is 24'6"(7.45m) too long? I can shorten length if required.

* for wooden floor(hard wood bearers/joists and 1" sheet floor), should floor be fixed directly to subfloor or should it be "decoupled" via rubber or other spacer? ie. does decoupling improve sonics?

I am hoping to avoid the theory and get straight to the definitive answers.I am all theoried out at this stage and want to finish modifying my music room.

A local HT design office suggested to add another plywood layer to the first layer over roofing felt and screwed into the first layer, but not the joists. I did this when building my home and am pleased with the result.
